Just got done building a custom 10/22.Boyd Blaster stock,Kidd barrel,receiver,bolt,single stage trigger,Mueller APV scope with weaver rings.Finally quit raining here in Ohio yesterdayso i was able to try this thing out.At 25yrds can't get on the paper hitting way low.The only way i could get it to hit i had to loosen everything up and i put a 1/4" shim under barrel then it was still 12"low left.Never built a gun before so any info would be deeply appreciated Thanks
